  • Page 5: Introduction

    Now you must be thinking 12 knobs and 12 switches make only a total of 24 possible controllable parameters. But the RAC12 is a lot more powerful than that : It allows you to control up to 384 Axe-Fx parameters. How ? Let’s now talk about the RAC12 Pages concept.

    AMP block parameters. Here is the RAC12 screen when on this page: A Page is a RAC12 concept describing a set of 12 knobs and 12 switches functionalities. What does that mean ? Let’s see what the default configuration of page 2 looks like : The 12 knobs now control different Axe-Fx parameters : The first knob (labeled DRIVE on the front panel) now controls the Preamp Bias parameter, the knob labeled BASS now controls the Low Resonance parameter…etc.

  • Page 12: Global Knobs And Global Switches

    5.4 Global knobs and global switches This is a very important concept in the RAC12. Just see it as a way to have identical knob/switch functions on every page, without having to configure each page. This can be very convenient by example for your main level knob.

  • Page 14 The Compare function will save the full preset data into the RAC12, thus the operation may take up to 9 seconds on the Axe-Fx XL and about 5 seconds on the Axe-Fx II, due to the slow speed of MIDI transfers.

  • Page 15: Page Mapping

    We strongly recommend using a good 5 pin DIN (DIN-5) MIDI cable, which has the 5 pins wired. With such cable, only one cable is needed to connect the RAC12 to your Axe-Fx : Just connect the Axe-Fx’s MIDI IN to the RAC12’s MIDI OUT.
